App'licationriled August 17, 1885. Serial No.174,653. (No model.)

Patented in England November 24, 1885, No. 14,401 g in Belgium December 15, 1885, No.`7l,014, and in France February 24, 1886, No. 172,554.

T all whom, it may con/cern.- y

Beit known that I, FREDERICK SI-IIoIILE, of St. Louis, Missouri, have made a newy and useful Improvement in PipeMolding Apparatus, of which the following is a full, clear,

and exact description.

The improvement relates to the means used in forming the socket end of the mold.

It also relates to the means for centering the 1o rammers at the upper end of the asks, and for guiding themin their upward movement through the lasks.

It also has reference to the means for forming the bead-ring, and for closing the upper I 5 end of the ask during the ramming.

The annexed drawings, making part of this specification, illustrate the various features of the improvements.

Figure 1 is an elevation, half in section on 2o the line 1 1 of Fig. 2, showing the ila/sk upon the ramming-stand as when the liask is to be rammed. Fig. 2 is a plan, half in section on the line 2 2 of Fig. 1, of the flask. Fig. 3 is a plan, half in section, the section being taken on theline 3 3 of Fig. 1, of the ramming-stand. `Fig. 4 is a view in perspective of the removable plate used upon the upper end of the ask in ramming it. As exhibited, the plate contains the prints for forming the recess for the 3o reception of the bead-ring, and the plate is shown resting in position upon the flask-body.

The same letters of reference denote the same parts. s,

The improvement in question is adapted more especially to flasks in which thepipes are cast the socket end downward,and to cluster asks, in distinction from single ilasks. Various features of the improvement, however, are adaptable to pipes otherwise cast 4o andV in single flasks, as will more fully appear upon further consideration.

A, Figs. 1, 3, represents the ramming-stand. Its frame-work consists,essentially,of thebase a, the upright a', and the top a2.

The cluster flask shown is a four-part one, and the ramming -stand is correspondingly constructed, to which end it is provided with four similar ramming appliances, as follows: Four spindles, a3 a3 a3 a3, are each stepped at a* a in the base a,

ed to be moved upward and downward a short distance in an opening, as, in the top d2. The ring ci, in turn, contains and upholds another ring, a9, whose shape externally is suited for forming the socket on the pipe to bc cast.' Arms am al at onel end are journaled upon bearings a upon the spindle, and atthe other end are jointed, respectively, to the arms a12 a, which extend upward, and are adapted to connect with and uphold the sleeve a5. The two pairs al au Iand al au form two toggles, which can be straightened and bent, and when straightened operate to lift the sleeve, and when bent operate to lower the sleeve upon the spindle.

One Inode of connecting the toggles with the sleeve is to let the upper ends of the arms au a bear upward against a shoulder, al, upon the spindle, and to connect the `arms a au by means of a bolt, a, which passes transversely through the arms c, the sleeve, and a slot, a, in the spindle. The slotis elongated vertically, to provide for the needed vertical movement of the sleeve.

By means of a lever, al, which is attached to the sleeve, and also connected with the arms am al, the spindle can be rotatedin its step and the toggles straightened and bent, the operation of this part of the construction being as follows: B represents the flask to be rammed. It is placed upon the ramming-stand so that its several compartments b l) b b shall respectively come properly into coincidence with the openings as a8 in the ramming-stand top a2. The

rammer C is dropped through the compartment b, and through the ring a7, and its lower end rests upon the spindle a3, which at that point is preferably supplied with averticallyadjustable screw, a, forjthe purpose of vertically adjusting the rammer. The sand D is placed in the compartment around-the rammer and the ring a. Then by throwing the free end of the lever a1G upward the rings on7 a are v lifted upon the rammer and within the comv partment b. The sand is thereby rammed in is done by means of the lever a1, which is vibrated horizontally, causing the sleeve and rings al a to be rotated reciprocatingly, and so as to part the sand from the rings, after which the lever al is thrown downward and the rings withdrawn. This is not done, however, until after the rammers are withdrawn. The sand in each of the compartments b b b b is similarly rammed, after which the sand throughout the main portion of the compartments is ready to be rammed. This is effected by means of the rammers C C C C, respectively, Figs. 1, 2. The rammers are similar to those described by me in the Letters Patent granted me November 27, 1883, numbered 289,035, and the ramming is effected by drawing the rammer upward from off the screw a and through the ring ci', and thence upward through the flask, substantially as in the Letters Patent referred to.

In the manipulation of the rammers several points must be attended to. In placing them in their respective compartments b, they must be properly centered at the top of the askcompartments. To this end the yoke G,which unitesthe rammcrs of the flask, is provided with a pin, G2, which, when the rammers are dropped into the compartments b,passes downward into a perforation, b', that is at the center of the ilask atthe top, and. that extends downward through the removable top E of the flask, and also through the part of the flask beneath the removable top. The engagement of the pin, as described, centers the clusters of rammers, and the various rammers are rcspectively properly centered in the compartments Z1 Z1 Z b by means of the frame F and the prints G. The frame is properly shaped, in the present instance being arranged to brace the rammers, as shownin Figs. 1, 2, respectively, centrally in their respective compartments, the frame for that purpose consisting of the four bars f f, attached to an interior frame, f/, Fig. 2, and at their ends f2 abutting against the rammers, and also being turned downward, as shown at f3, Fig. 1, to t between the print-s G and the rammer. The prints Gare annular in form', and in diameter are equal to that of the largest part of the rammer, or of that of the iinished mold at the -upper end. They are beveled at g, and are furnished with a ange, g', Fig. 1,wl1ich comes against the under side of the removable plate E. This plate or top has openings e, to receive the prints from beneath, as represented in Figs. 1, 2, 8. The openings are respectively coincident with the compartments b.

The top E is adapted to be secured during the `ramming and, by means of suitable clamps, to

the flask-body b. The top E holds the prints down against the upward pressure exerted by the rammer. The frame F, by means of the buttons f3, Figs. 2, 8, is adapted to be held down upon the top E. Byl this means, when the sand within the compartments is being crowded upward by the action of the rammer, the top E both prevents the sand from being uplifted from its place and holds the prints and centering-frame F down in position. The flask being rammed is made ready for the casting operation, to which end the socket-form.-

ing rings are drawn downward by means of the ram mi ngstand mechanism, the bead-rings are placed in position, and the mold blackwashed and set upon the bottom and clamped thereto, and then swung into the oven and dried, after which it is hung upon the pit-wall, the cores inserted, and the appliances at the upper end of the flask for completing that part ot' the mold, and for directing the flow of the molten metal, are placed in position.

The flask is set upon and removed from the ramming-stand in the ordinary manner and with the customary means.

The flask shown is made in four parts. Each pair of said parts is divided vertically and diametrically and hinged togetherone pair at 1130, the otherpair at bm. The inner and contiguous parts of each pair may be riveted or otherwise secured together.

The iiask is hung upon the pit-wall by means of the hanger O'and brace P.
